    DeepSeek-V4.1-Flash vs GLM-5.3-Flash on DGX Spark: which model is actually smarter?

    Calendar October 3, 2026
    Llm, Dgx-Spark, Benchmarks, Deepseek, Glm
    DeepSeek’s own benchmarks say V4.1-Flash beats GLM-5.3-Flash; independent measurement (Artificial Analysis) and several NVIDIA DGX Spark forum users say the opposite. Both impressions are traceable; here is the evidence.
